This is probably one of the subjects that will never be resolved to everyone's satisfaction. For what it's worth Packard switched to the capsule type thermostat during 1953 production and their reasoning was because increased pressure up to a certain point would tend to keep the bellows thermostat closed longer before it would fully open resulting in a potential overheating issue. Here is their explanation.
